At Upfit Supply, we’re committed to making van upfitting simple and effective. Today, we’re taking a detailed look at the Unboxing Holman Ladder Rack Mount Kit for RAM ProMaster. Whether you’re running HVAC, electrical, or any mobile trade service, the right ladder rack system is crucial for optimizing your workflow. But before you can install that drop-down ladder rack, you need the right mounting hardware.

That’s where this product comes in. The Holman Mount Kit for the RAM ProMaster is designed specifically for this vehicle, ensuring a secure, factory-fit installation. Let’s get into what’s inside the box, how it’s used, and why it’s a must-have for anyone adding a Holman ladder rack to their ProMaster van.

What’s in the Box? | Unboxing Holman Ladder Rack Mount Kit for RAM ProMaster

We opened the box and found everything packaged neatly and securely. The mount kit includes all the brackets, rails, and hardware needed to attach a Holman drop-down ladder rack to any RAM ProMaster model—standard roof or high roof, all wheelbases.

Here’s what you’ll find:

  • Feet and mounting brackets (powder-coated white to match Holman ladder racks)
  • Mounting rails (aluminum extrusions used to span factory roof points)
  • Galvanized hardware kit: bolts, washers, lock washers, and slider bolts
  • Detailed installation guide with illustrations
  • Three-year factory warranty card

The build quality on all components is solid, with everything powder-coated or galvanized to withstand harsh conditions. We especially appreciate that everything is labeled and quality control-stamped, giving confidence in a smooth install.

Designed for the RAM ProMaster

It’s important to note that this mounting kit is vehicle-specific. The RAM ProMaster has unique factory mounting locations on the roof, and Holman designed this kit to work precisely with those points.

You’ll need this kit before installing any Holman drop-down ladder rack. The ladder rack itself is universal across several van platforms, but the mounting system must match the van model. This kit—part number 4081P—is your go-to for any ladder rack install on the ProMaster.

Key Features | Unboxing Holman Ladder Rack Mount Kit for RAM ProMaster

Let’s break down the notable features and components that set this kit apart:

  • Factory-Fit Compatibility: Installs directly into OEM mounting points—no drilling or modifications required.
  • Durable Powder-Coated Finish: All brackets come in white to match Holman ladder racks and resist corrosion.
  • Aluminum Rails: These extrusions help bridge mounting gaps, particularly for the front locations on the van.
  • Comprehensive Hardware Pack: Includes all bolts, nuts, washers, and even slider bolts for custom adjustments.
  • Universal Rail Extrusions: Mounting rails are mirrored for both left and right sides, making orientation easy.

These features not only ensure a secure and weather-resistant installation, but also reduce install time significantly.

Installation Overview | Mount Your Drop-Down Ladder Rack with Confidence

Before you get started, it’s always a good idea to review the illustrated instruction manual included in the kit. Holman does an excellent job providing both clear line drawings and a full parts list.

Here’s what the general process looks like:

  1. Identify factory mounting points on your RAM ProMaster’s roof.
  2. Use the brackets and mounting feet to connect the Holman hardware to the van.
  3. For the front portion, attach the extruded aluminum rails to span across two factory points—this supports the drop-down rack’s front arm.
  4. Align the rack system and secure using the galvanized bolts and hardware provided.
  5. Double-check tightness and spacing before finalizing the install.

This kit is built to work in tandem with Holman drop-down racks, which is why each component is so vehicle-specific. Although the ladder rack itself may be reused across van models, the mounting kit must match your van.

Why You Need This Kit | Unboxing Holman Ladder Rack Mount Kit for RAM ProMaster

If you’re installing a Holman drop-down ladder rack on a RAM ProMaster, this kit isn’t optional—it’s essential. It’s the bridge between your rack and the van. Without it, you won’t have the support points or rail spacing needed to properly mount your rack.

Here’s what makes this kit valuable:

  • Eliminates guesswork with vehicle-specific design
  • Saves time on installation thanks to factory-matched hardware
  • Provides peace of mind with a secure, bolt-in setup
  • Ensures alignment and strength, especially for heavier or longer ladders

Whether you’re working solo or outfitting an entire fleet, having the correct parts makes the process faster and more reliable.
